Research progress of medical X-ray protective materials
The mechanisms of interaction between medical X-ray and biological systems, and the principles of physical protection, were briefly introduced. The research progress of flexible composite materials with medical X-ray shielding capability was analyzed. The performance characteristics of X-ray radiation-shielding functional particles such as lead, bismuth, and tungsten, along with polymer substrates, were discussed. The advantages and disadvantages of fabrication methods including coating, sol-gel, and spinning techniques were summarized. It was indicated that the existing X-ray protective materials had great significance in enhancing protective effectiveness and usability, but they faced challenges in performance optimization and cost control. Future research should focus on the development of novel functional particles, structural design optimization of composite materials and exploration of environmentally friendly and efficient shielding materials, so as to further improve the performance and broaden application prospects of medical X-ray protective materials.
